This article guides you through using CCN to associate VPCs crossing accounts.

Prerequisites

  • Both accounts are eligible for the beta testing of the Cloud Connect Network (Here we take account A and B as examples).
  • having created the VPCs for association.
  • Eliminating conflicts between the VPC subnet IP range and IDC IP range.

Step 1: Creating a CCN Instance in Account A

  1. Log in to Tencent Cloud Console using account A, select Products -> Networking -> Virtual Private Cloud to enter the VPC console.
  2. Click Cloud Connect Network in the left pane to enter the Cloud Connect Network management page.
  3. Click Create.
  4. Enter the CCN instance name and notes in the pop-up window.
  5. Associate a network instance (or do it after the CCN is created).
  6. Click OK to create a CCN instance.

Step 2: Using Account B to Apply for the VPC Association.

  1. Log in to Tencent Cloud Console using account B, select Products -> Networking -> Virtual Private Cloud to enter the VPC console.
  2. In the VPC list, click the VPC ID to be associated.
  3. In the details page, click Associate Now.
  4. In the pop-up window, select Other Account and enter the account A ID and the CCN instance ID.
  5. Click OK to send the association request to the account A.

Step 3: Accepting the Association Request in Account A

  1. Log in to Tencent Cloud Console using account A, select Products -> Networking -> Virtual Private Cloud to enter the VPC console.

Step 4: Checking the Route Table

If the IP ranges of the associated network instances conflict, there will be an invalid route. You can check it as follows:

  1. In the CCN list, click the CCN ID of the route for the check.
  2. In the details page, click Route Tables to view the route table.
  3. Check if there is any invalid routing policy.
  4. For details of routing conflicts, see Use Limits. To enable a conflicted route, see Enabling a Route.

Step 5: Setting Cross-region Bandwidth Cap (Optional)

  1. In the CCN list, click the CCN ID for which to set the bandwidth.
  2. In the details page, click the Monitoring tab to view the metrics of the CCN.
  3. Select the region for which to set the outbound bandwidth cap.
  4. Set the outbound bandwidth cap for each region (1 Gbps by default).

Communications between CCN instances incur fees. For pricing details, see Pricing.
